' OIL- BURNER.

Specification of Letters Patent, Patented May 21 1912.

Application med- July 27, 1908, semi No. 445,496. Renewed July 12, 1510. Serial No. 571,657.

To all whom it may concern:

Be it known that I, MIL'mNA. Fnsnun, a citizen'of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners,

2 isasectional view of a furnace .showing the oil burner in position.

Referring to the drawing, 1 indicates a furnace, supported upon a suitable base 2, upon which rests, at the center of the furnace, a standard 3 from which project laterally upper and lower bearings t, 5. Supported upon said ,jbearingsare bushings 6, m which rotates a vertical tube 7, upon which is secured a pulley 8 driven by a belt 9 from any suitable source of power. The specific means for rotating the tube is immaterial to the resent invention. Through said tube exten s centrally a stationary oil 'supplypipe 10 to the top of which secured aconical spreader 21. The oil passing through, said pipe 10 flows 'down said spreader on to the upper flat surface of a deflector wheelll having a hub 12 secured to the tube and havingalso an outer rim, 13. The top of saidwheel is closed by acap 14 and to said rim are secured a number, as four, of. tapering tubes' 15. By the rapid rotary motion imparted to the tube 7 and therefdre to the wheel, the oil-is forced against the inner surface of the rim 13 and down oil conduits 16, one leading into each tube 15. 4 v

Surrounding the burner proper are upper and lower concave partit ions 17 18, the lower partition 18 being formed near the outer edge with openings 19 for admitting air into the narrow space between the partitions. In this space the air becomes highly heated by reason of the high temperature of the upper partition 17, and'the heated airpasses upward between the hub 12 andthe rim 13 of the'lwheel. Hence it passes into the tubes 15 by means of holes 23 in saidrim registering with the inner ends of said tubes. It is by reason of the rapid rotary motion of these tubes that the air is drawn through the openings 19 in thelower parti tion into the space between the two partltions. The oil and air are thenthrown outwardwithgreat velocity, and 'on --account of thls velocity the oil is very finely r'a'tom 'ized and ,conmingled with the hot air. It

is thus burned in a very effective manner. I

I find that for the successful operation of this burner the air and vaporized oil issuing from the rotating conduits must have a clear flight of a lengthnot less than the length of the conduits, before impinging upon a wall or any other obstruction, otherwise the oil will carbonize and deposit carbonupon t'he obstructing wall.

I claim l. -In an oil burner,the combination of bearings, a vertical tubular shaft in said he airings-means for rotating said shaft in s .id bearings, a deflector wheel secured at the upper" end of said shaft and having a depending outer rim spaced from said shaft, and outwardly extending tubessecured to said rim and communicating with the space between said rim and shaft, said wheel having oil conduits leading into the respective I tubes, substantially as described. v

2. In an oil burner, the combination of bearings, a vertical tubular shaft in said bearings, means for rotating said shaft in said bearings, a deflector wheel secured at the upper end of said shaft and having a depending outer rim spaced from said shaft, :1 cap inclosing the top ofthe'wheel and forming therewith an oil chamber, and outwardly extending tubes secured to said rim. and communicating with the space between said rim and shaft, said wheel .having oil conduits leading into'the respectivetubes, substantially as described.

3. In an oil burner, the combination of bearings, a vertical tubular shaft in said bearings, means for rotating said shaft in said. bearings, a deflector wheel secured at the upper end of saidshaft, an oil tube lead- .ing centrally through said hollow shaft, and a conical spreaderzsecured to the top ofsaidoil tube and discharging on to s'ald w'heel,

,substantially as described.

4. In a furnace, the combination of upper and lower partitions therein, a centrifugal oil burner above the upper partition, and means for admitting air into the space be-- tween the partitions at points remote from said oil burner, substantially asdescribed.

5. Ina furnace, the combination of upper and lower concave partitions, a stand below said partitions, bearings supported by sa d stand, a vertical tube rotatab y supported 1n for rotating said tube, substantially as described.

6. In an oil burner, the combination of a vertical shaft, means for rotating said shaft, a deflector secured upon the upper 'portion of said shaft, and having a ring spaced from the shaft, said deflector having air conduits leading outwardl from the space between said ring and sha t, and means for supplying oil to said' conduits, substantially as described.

7. Inan oil burner, the combination of a Vertical shaft, means for rotating said shaft, air co duits rotated with said shaft, arranged to receive air at the inner end thereof, and means for conveying oil into the inner ends of said conduits, substantially as described;

8. The combination of a furnace, anoil burner therein, having conduit-s for the air and oil of combustion, and means for rotating said conduits, the conduits being more remote from the Wall of the furnace than the length ofsaid conduits, substantially as described. 4 v

9. In an oil burner, the combination of a rotatable vertical shaft, a deflector therefor comprising a cap andair conduits both rotatin'g with said shaft, and an'oil pipe (liscliarging into said deflector beneath said cap, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
